UFC was scheduled to make its debut on Fox later in the evening with a heavyweight title fight, but the first several bouts on the card appeared only via Fox Deportes and an online video stream on Facebook. The first seven bouts included four affairs that ended in a knockout or submission:

• Ricardo Lamas submitted Cub Swanson with a head-and-arm choke in the second round of an action-packed bout between featherweights. Both fighters attacked with abandon, throwing kicks and big punches to send each other retreating across the cage at points. Lamas had to survive multiple guillotine chokes before finally catching Lamas with the arm-triangle.

• Dustin "The Diamond" Poirier used an anaconda choke to force a tapout from featherweight Pablo "The Scarecrow" Garza.

• DaMarques Johnson knocked out Clay Harvison in the first round of their battle of welterweight alumni from The Ultimate Fighter. Johnson dropped Harvison with a left hook and followed with a single right hand to the face to finish the bout.

• Robert Peralta recorded a third-round technical knockout of featherweight Mackens Semerzier. Peralta ended the fight with several seconds of ground-and-pound strikes after he apparently knocked down Semerzier, who was desperately clinging to his opponent's leg in an attempt to survive. Replays suggested that Semerzier went down initially because of an accidental headbutt that was missed by referee John McCarthy.

• Darren Uyenoyama won a unanimous decision to send Norifumi "Kid" Yamamoto to his third loss in four fights. The clash of bantamweight veterans from the Japanese circuit saw Uyenoyama threaten Yamamoto in the first and second rounds with rear-naked choke attempts. Yamamoto on rare occasions flashed the punching power that made him a superstar of smaller weight classes a few years ago, but other than a couple of flashy takedowns, he was outgrappled by Uyenoyama, who controlled the action from back mount for long stretches.

• Aaron Rosa defeated fellow light-heavyweight Matt Lucas via majority decision. McCarthy deducted a point from Lucas for losing his mouthpiece multiple times, resulting in two 30-26 scores for the winner, as well as a 28-28 draw on one scorecard.

• Alex Caceres, an alumnus of TUF Season 12, earned a victory in his bantamweight debut with a unanimous decision against Cole Escovedo.

• Mike Pierce took home a unanimous decision against welterweight Paul Bradley.
